IMPEDANCE CHARACTERISTICS OF POLYFURAN FILMS*
摘要:
Electrochemical impedance spectroscopy (EIS) was first used for the characterization of polyfuran (PFu) films thathad been formed electrochemically on an Au electrode. The polyfuran was measured in high oxidation state, intermediateoxidation state and reduction state, respectively. As the oxidation level is increased, the ionic conductivity of PFu/BF4-increases. And impedance studies on PFu show that the anion BF4- appears to be mobile with a high diffusion coefficient of approximately 10-8 cm2·s-1.
